This paper is mainly concerned with the coupling dynamic analysis of a complex spacecraft consisting of one main rigid platform, multiple liquid-filled cylindrical tanks, and a number of flexible appendages. Firstly, the carrier potential function equations of liquid in the tanks are deduced according to the wall boundary conditions. Through employ- ing the Fourier-Bessel series expansion method, the dynamic boundaries conditions on a curved free-surface under a low-gravity environment are transformed to general simple differential equations and the rigid-liquid coupled sloshing dynamic state equations of liquid in tanks are obtained. The state vectors of rigid-liquid coupled equations are composed with the modal coordinates of the relative potential func- tion and the modal coordinates of wave height. Based on the B ernoulli-Euler beam theory and the D＇Alembert＇s prin- ciple, the rigid-flexible coupled dynamic state equations of flexible appendages are directly derived, and the coordi- nate transform matrixes of maneuvering flexible appendages are precisely computed as time-varying. Then, the cou- pling dynamics state equations of the overall system of the spacecraft are modularly built by means of the Lagrange＇s equations in terms of quasi-coordinates. Lastly, the cou-piing dynamic performances of a typical complex spacecraft are studied. The availability and reliability of the presented method are also confirmed.

In this paper we mainly study the ruin probability of a surplus process described by a piecewise deterministic Markov process （PDMP）. An integro-differential equation for the ruin probability is derived. Under a certain assumption, it can be transformed into the ruin probability of a risk process whose premiums depend on the current reserves. Using the same argument as that in Asmussen and Nielsen, the ruin probability and its upper bounds are obtained. Finally, we give an analytic expression for ruin probability and its upper bounds when the claim-size is exponentially distributed.

Angiotensin Ⅱ(Ang Ⅱ) is involved in endothelium injury during the development of hypertension. Tribulus terrestris(TT) is used to treat hypertension, arteriosclerosis, and post-stroke syndrome in China. The present study aimed to determine the effects of aqueous TT extracts on endothelial injury in spontaneously hypertensive rats(SHRs) and its protective effects against Ang Ⅱ induced injury in human umbilical vein endothelial cells(HUVECs). SHRs were administered intragastrically with TT(17.2 or 8.6 g·kg^(-1)·d^(-1)) for 6 weeks, using valsartan(13.5 mg·kg^(-1)·d^(-1)) as positive control. Blood pressure, heart rate, endothelial morphology of the thoracic aorta, serum levels of Ang Ⅱ, endothelin^(-1)(ET^(-1)), superoxide dismutase(SOD) and malonaldehyde(MDA) were measured. The endothelial injury of HUVECs was induced by 2 × 10–6 mol·L^(-1) Ang Ⅱ. Cell Apoptosisapoptosis, intracellular reactive oxygen species(ROS) was assessed. Endothelial nitric oxide synthase(eN OS), ET^(-1), SOD, and MDA in the cell culture supernatant and cell migration were assayed. The expression of hypertension-linked genes and proteins were analyzed. TT decreased systolic pressure, diastolic pressure, mean arterial pressure and heart rate, improved endothelial integrity of thoracic aorta, and decreased serum leptin, Ang Ⅱ, ET^(-1), NPY, and Hcy, while increased NO in SHRs. TT suppressed Ang Ⅱ-induced HUVEC proliferation and apoptosis and prolonged the survival, and increased cell migration. TT regulated the ROS, and decreased mR NA expression of Akt1, JAK2, PI3Kα, Erk2, FAK, and NF-κB p65 and protein expression of Erk2, FAK, and NF-κB p65. In conclusion, TT demonstrated anti-hypertensive and endothelial protective effects by regulating Erk2, FAK and NF-κB p65.
